BACKGROUND: The purpose of this study was to assess the results of arthroscopic bridging repair using a human dermis allograft in the treatment of massive irreparable rotator cuff tears. METHODS: From November 2009 to April 2011, 12 patients underwent arthroscopic bridging repair using a human dermis allograft in the treatment of massive irreparable rotator cuff tears. Patients were followed for an average of 33.9 months. Clinical outcome was evaluated preoperatively and postoperatively using the mean University of California, Los Angeles (UCLA) score and the Korean Shoulder Scoring System (KSS). Magnetic resonance imaging (MRI) was performed postoperatively at an average of 6.5 months. RESULTS: At a mean follow-up of 33.9 months (range, 25 to 42 months), 11 out of 12 patients were satisfied with their procedure. Patients showed significant improvement in their mean modified UCLA score from 15.9 preoperatively to 29.4 postoperatively (p=0.001). The mean KSS score improved from 45.6 preoperatively to 80.5 postoperatively (p=0.002). In MRI studies, 9 out of 12 patients had full incorporation of the graft into the native rotator cuff remnant. To date, there has been no intraoperative or postoperative complication from the graft procedure, such as infection or allograft rejection, in any patient. CONCLUSIONS: Arthroscopic bridging repair using a human dermis allograft can be considered as an option in treatment of select cases of massive irreparable rotator cuff tears, resulting in high patient satisfaction.

Arteriovenous malformation of the uterus is rarely encountered. It is potentially lethal because of profuse, uncontrollable bleeding at the time of diagnostic dilatation and curettage. To our knowledge, only 38 cases of localized uterine arteriovenous malformation have been reported in English and Korean literature. Recently we experienced a case of uterine arteriovenous malformation in a 28-year-old multiparous woman. Under the clinical impression of uterine tumors or arteriovenous malformation, a total hysterectomy was done. Gross examination demonstrated a vascular nature of the mass in the posterior wall of the fundus. Microscopically, there was an ill-defined mass composed of numerous irregular, anastomosing large vessels with various diameters.

The clinicolaboratory findings, cardiac catheterization, and outcome of operation were analyzed in 78 patients with tetralogy of Fallot, which were diagnosed by echocardiography, cardiac catheterization, and a cardiac angiography and confirmed by operation at Dong San Hospital, Keimyung University, during a 4(1/2)-year period from January 1984 to June 1988. The following results were obtained : 1) Out of the 78 cases, 45 were male and 64 were female. 2) The electrocardiogram showed right axis deviation in 71 cases(91%) and right ventricular hypertrophy in 66 cases(84.6%). 3) Chest X-ray revealed that, the cardiothoracic ratio was normal or decreased in 68 cases(87.3%), and cardiac apex elevation was noticed in 57 cases(73%). 4) Pulmonary stenosis were chiefly valvular and infundibular type(53.8%). 5) The associated heart diseases with TOF were patent foramen ovale(64.1%), right sided aortic arch(19.2%), and secundum ASD(10.3%), in that order. 6) There was an intimate correlation between secondary polycythemia and thrombocytopenia. 7) Among the 78 Cases, 73 cases had total correction, 1 case had shunt operation, and 4cases had total correction after shunt operation. The highest mortality rate occurred in the cases of total correction after shunt operation(25%). The cases with a main pulmonary artery size of 1/3 to 2/3 against, the aorta had a higher mortality than the other group, and no cases expired in the group with a ratio of more than 2/3. The overall surgical mortality was 8.9%.

The localizations of efferent and afferent neurons were observed following injection of neural tracers, cholera toxin B subunit (CTB) and wheat germ agglutinin-horseradish peroxidase (WGA-HRP) into the rat thymus with ages. Thirty Sprague-Dawley rats were examined at 3 weeks, 5~6 and 20 months of age. After survival times of 48~96 hours following injection of neural tracers, the rats were perfused and their brain, spinal cord, sympathetic ganglia, dorsal root ganglia and vagal ganglia were frozen sectioned (40 mm). These sections were stained by CTB immunohistochemical and HRP histochemical staining methods, and observed with polarized dark and light microscope. The results were as follows: 1. WGA-HRP and CTB labeled parasympathetic neurons were bilaterally seen in the nucleus ambiguus and medullary reticular formation of medulla with all ages. 2. WGA-HRP labeled sympathetic neurons were bilaterally labeled in superior cervical ganglia, middle cervical ganglia, stellate ganglia and T4-8 sympathetic chain ganglia. The number of labeled sympathetic neurons was increased in the thymus at 20 months of age. According to the aging, sympathetic neuronal processes were more developed, and the nerve fibers were coarse and more branched. 3. WGA-HRP labeled sensory neurons were bilaterally observed within the vagal and C1-6 dorsal root ganglia. The number of labeled sensory neurons was decreased in the thymus at 20 months of age.

We report a case of subcutaneous phaeohyphomycosis caused by Exophiala(E,) jeanselmei in a 66-year-old female, who showed a mild tender, 4.5x3.5cm sized, erythematous cystic mass with satellite lesions on the left forearm for 4 months. Histopathologically, suppurative granulomatous inflammation, brownish conidia in a chain and hyphae were observed. Fungal culture grew out the typical black-gray velvety colonies of E. jeanselmei after 2 weeks. The isolate grow well at 25 C, but very poorly at 37 C. No growth could be observed at 40 C. Sporulation adequate for evaluation was present on the malt extract agar. We confirmed E. jeanselmei by colony and microscopic morphology, temperature tolerance and sugar assimilation tests. The patient had been treated with itraconazole for 6 momths. Complete remission was observed.

PURPOSE: To determine the frequency of diseases of the hip and pelvis, as seen of plain radiography of the lumbar spine in patients with suspicious lumbar disease, and to evaluate the methods used for lumbar spine radiography in Korea. MATERIALS AND METHDOS: Sixty university and training hospitals were randomly selected and asked to describe the projections, film size and radiographic techniques employed for routine radiography in patients with suspected disease of the lumbar spine. Plain radiographs of 1252 patients, taken using 14"x17"film and depicting both hip joints and the lumbar region, were analysed between March 1999 and February 2000. RESULTS: In 15 patients (1.2%), the radiographs revealed hip or pelvic lesions, confirmed as follows: avascular necrosis of the femoral head (n=11, with bilateral lesions in four cases); sustained ankylosing spondylitis (n=2); acetabular dysplasia (n=1); and insufficiency fracture of the pubic rami secondary to osteoporosis (n=1). In 11 of the 20 hospitals which responded, 14"x17"film was being used for lumbar radiography, while in the other nine, film size was smaller. CONCLUSION: Plain radiography of the lumbar spine including both hip joints, may be a useful way to simultaneously evaluate lesions not only of the lumbar spine but also of the hip and/or pelvis.

PURPOSE: To evaluate the accuracy of the SRK II formula for the AMO Array(R) multifocal intraocular lens (Array lens) power calculation according to axial length. In case of refractive error more than +/- 1.0 diopter (D), we compared the accuracy of the SRK II with that of other formulas. METHODS: Participants were 178 eyes (142 patients) received the Array lens. These were divided into 3 subgroups based on axial length. Group I had 21 eyes of short axial length (less than 22.0 mm). Group II had 133 eyes of average axial length (more than 22.0mm below 24.5mm). Group III had 24 eyes of long axial length (more than 24.5mm). The difference between preoperative predicted refractive value and postoperative manifest refractive value were calculated. We compared the accuracy of the SRK II and that of SRK/T, Holladay formulas in case of refractive error more than +/- 1.0D. RESULTS: Three eyes (14.2%) in Group I, 14 eyes (10.5%) in group II and 15 eyes (62.5%) in Group III showed refractive errors more than +/- 1.0D. Fifteen eyes (62.5%) in Group III were significantly reduced to 7 eyes (29.1%) with using SRK/T, Holladay formulas. CONCLUSIONS: SRK II formula had better predictive accuracy in axial length less than 24.5mm with Array lens. But it is better to apply SRK/T or Holladay formulas when axial length is more than 24.5mm.
